Answer:
132 people bought balcony seats and 450 people bought ground seats.
Step-by-step explanation:
We want to solve the system of equations:
[tex]\left\{ \begin{array}{ll} 15b+10g=6480 \\ b+g=582 \end{array} \right[/tex]
We can solve this by using substitution. From the second equation, we can subtract b from both sides:
[tex]g=582-b[/tex]
In the first equation, we can divide both sides by five:
[tex]3b+2g=1296[/tex]
Substitute:
[tex]3b+2(582-b)=1296[/tex]
Distribute:
[tex]3b+1164-2b=1296[/tex]
Simplify:
[tex]b+1164=1296[/tex]
Solve for b:
[tex]b=132[/tex]
Using the modified equation again, substitute:
[tex]g=582-(132)[/tex]
Evaluate:
[tex]g=450[/tex]
Therefore, 132 people bought balcony seats and 450 people bought ground seats.
